ARTIFICIAL-SILK AND LIKE SPINNING MACHINE.

Application filed September 15, 1926, Serial No. 135,645, and in GreatBritain September 26, 1925.

This invention-is for improvements in or relating to artificial silk andlike spinning machines of the type having the filament directed into thespinning box by a funnel, which is usually of glass, and which reachesinto the interior of the spinning box and has to be removed therefromwhen the spinning box is to be detached, or when the cake of artificialsilk is removed, even if the box is not detached; for this purpose thefunnel is carried in a movable mounting which is adapted to support thefunnel in its operative position and in an inoperative position in whichit is clear of the spinning box, and the mounting permits the funnel tobe readi'ly moved by a swinging or like movement between such positionswithout disturbing the setting of the funnel in the mounting. Theinvention has for one of its objects. to provide an improvedconstruction of machine, of this type, in which the movement of thefunnel to and from its operative position inside the spinning box iseffected in a more convenient and efficient manner than has heretoforebeen proposed.

According to the primary feature of the present invention there isprovided a machine of the above type which is characterized in that thefunnel mounting is so constructed and arranged in relation to thespinning box that the withdrawal movement of the funnel from. itsoperative position to a position outside the spinning box, and thereturn movement from the said outside position to operative position,are substantially in the direction along the length of the funthemounting is so constructed. and arranged that subsequent to the saidwithdrawal movement the funnel is moved clearof the spinning box in adirection laterally of the length of the funnel spout or stem. It willbe appreciated that by the employment of the pres ent invention thefunnel is, moved into and out of its operative position readily andwithout risk of breakage, and that, furthermore, since its actualwithdrawal movement from its operative position to a position outsidethe spinning box is substantially in the direction along the length ofthe funnel spout, the aperture in the cover of the spinning box throughwhich the stem has to pass can be made of dimensions closelyapproximating to those of the spout and C0nsequently the risk of acidsplashing outof the spinning box through this aperture is minimized.

The motion may be imparted to the fun- I by a side of the frameworkwhichis connected by other sides to the aforesaid stationary side. Inone construction the articulated framework comprises parallel motionsides whereof the pivots which are transe lated during the parallelmotion lie at the ends of a side which carries the funnel and also liein a plane parallel to, or coincident with, the longitudinal axis of thefunnel spout. 'This parallel motion framework afford's a simple andcompact mechanism for effecting the desired result. The mounting ispreferably so disposed that when the funnel is in its operative positionthe movable sides lie slightly to one side of the dead centre positionin which opposite sides are furthest apart and through which dead centreposition the sides movein withdrawing the funnel from the spinning box.

For a more complete understanding ofthe invention there will now bedescribed, by way of example only and with reference to the accompanyingdrawings. one constructional form of funnel-carrying mechanism accordingto the invention. It is to be understood, however, that the invention isnot restricted to the precise constructional details set forth.

In these drawings Figure 1 is a side elevation of the mechanism showingthe parts in full lines in their operative position and in chain linesin their fully withdrawn position, and

Figure 2 is.an end elevat on of the mechanism, partly in section, on theline 22 of Figure 1.

Like reference numerals indicate like partsthroughout the drawings.

In the drawings a portion of the centrifugal spinning box of anartificial silk spinning machine is illustrated at 10 and a covertherefor at 11. The traverse rail is shown at 12 and it will, beunderstood that, there is relative vertical reciprocation between thespinning box and the traverse rail in or der to lay the filament in aseries of coils inside the spinning box. The mouth or, intake portion ofthe funnel'is indicated at 13 and the spout or stem thereofat 14, thelatter being arranged vertically. The funnel iscarried in an eboniteholder 15 which is threaded on its exterior and is loosely received inan aperture in a horizontal extension 16 from a vertical member 17. Theholder and funnel are adjusted in position in the extension 16 by meansof nuts 18 and 19, one of which is situated above and the other belowthe said extension. Mounted on the traverse rail 12 is a bracket 20, andthe member 17 and bracket 20 are connected by two pairs of side members21 and 22, and 23 and 24 respectively, the sides in the one pair beingparallel to those in the other pair so that there is constituted anarticulated framework consisting of the stationary bracket 20,themovable member 17 (which always remains Vertical) ,and the parallelsides 21, 22,

. 23 and 24. At each of the joints there is-a pivot pin 25 having anenlarged head 26 at one end and a reduced screw-threaded portion 27 atthe other end which receives a securing nut 28. Under each nut there isa spring washer 29 and a plain Washer 30 for providing the requisiteamount of friction to retain the parts in any position in which the maybe set, while at the same time only cal ing for a slight efl'ort on thepart of the operator to alter the setting. It will be seenthat the twopivot pins 25 in the link 17 are situated vertically one above the otherand likewise the two pivot pins 25 in the bracket 20 are situated onevertically above the other. The whole of the mechanism is preferablymade of acid-resisting material.

It will be seen that when the arts are in the position shown in fulllines 1n Figure 1, which is the operative position, the arallel sides21, 22, 23 and 24 lie slightly be ow thehorizontal position, namely thedead centre osition in which .the member 17 is furthest rom the bracket20.. Obviously the arallel sides 21, 22, 23 and 24 have to pass t roughthis dead centre position in passing to their completely withdawnposition which is illustrated in chain lines in Figure 1. There appearsin Figure 1 an arc of a circle which indicates the path of movement ofthe point 31 at the lower end of the stem of the funnel. When this pointhas reached the position 32 it will be seen that it is clear of thespinning box and the ,cover and that in reaching this position it hasexperienced an amount of lateral displacement equal to the distance 33.The aperture 34 in the cover 11, therefore, has toaccommodate this lat-.eral displacement, but'as-such displacement is extremely small it willbe appreciated that the aperture 34 can be kept quite dmall,

which isan important point in preventing acid from splashing out of thespinning box.-

In continuing its movement from the posi-' tion 32 to the chain lineposition shown in Figure l, the funnel is-swept through an -arc whichapproaches more and-more nearly to the horizontal and thusis carriedclear. laterally of the spinning box.

It is to be understood that the'invention is not restricted to theprecise constructional details set forth. For instance, it is notessential for the funnel to be maintained vertical in its Withdrawnposition; nor is it essential to employ a parallel motion framework.

I claim I 1. In an artificial silk or like spinning machine of the typedescribed, the combination with a funnel of a mounting therefor which isso constructed and arranged-in relation to the spininng box that thewithdrawal movement ofthe funnel from its operative position to aposition outside the spinning box, is a continuous movement which,initially, is substantially in the direction along the lengthof thefunnel and subsequently is in a direction laterally of the length ofthe:

funnel.

2. In an artificial silk or like spinnin machine of the type described,a funne mounting comprising an articulated framework whereof one side isrelatively station shy and the other sides move to carry the funnel toand from operative position relatively to'the spinning box, saidframework being so situated relatively to the spinning box that thewithdrawal movement of the funnel from its operative position to aposition outside the spinning box is subtantially in the direction alongthe length of outside the spinning-box is-substantially in the directionalong the length of the funnel, and that-subsequent to the saidwithdrawal -movement the funnel is moved clear of the,

spinning box in a direction laterally of the length of the funnel.

4. In an artificial machine of the type described; a funne an; or likespinnin the funnel and that subsequent to the said mounting comprisingan articulated frame work whereof one, side carriesthe funnel,

and other sides, which have aparallel 1110- tion, are pivoted to saidfunnel-carrying side by pivots which lie in a plane parallel to thelongitudinal axis of the funnel.

'5. In an artificial silk or like spinning machine of the typedescribed, a funnel mounting comprising a four-sided articulatedframework whereof one side carries the funnel, the opposite side isrelatively stationary and the pivots connecting the other palr of sidesto the funnel-carrying side lie in a plane parallel to the longitudinalaxis of the funnel. 1 -v 6. In an artificial silk or like spinningmachine of the type described, a funnel mounting comprising anarticulated framework whereof one side is relatively statio'nary and theother sides'move to carry the funnel to and from operative position inthe spinning box, said framework being so disposed relatively to thespinning box that when the funnel is in its operative position themovable sides .of the framework lie 4 slightlyto one side of the deadcentre. position in which opposite sides are furthest apart, throughwhich dead centre position the sides move in withdrawing the funnel fromthe spinning. box.

- 7. In an artificial silk or like spinning machine of the typedescribed, an articulated funnel mounting which is so constructed andthe spinning box in a direction laterally of the length of the funnel.

In testimony whereof Ihfliic my signature.
